Description

Device for separable joining and articulated a brush to clean glass moons with one arm of the windshield wiper.

State of the art

Brushes for cleaning glass moons of vehicles are always articulated together with the arm of the windshield wiper that performs the work movement so that the brush can perform a swing movement with respect to the wiper arm, finding its swing axis transverse to the longitudinal extension of the arm of the windshield wiper and transverse to the direction of a force that acts on the brush, force with which the brush is placed On the crystal moon. This articulated joint between the brush and the wiper arm is of great importance. Market Stall that the crystal moon to clean, spherically curved so generally, it does not show the section of a spherical surface, during its washing movement, the brush must be able to adapt continuously to the corresponding position and the path of the Crystal moon surface. Therefore, articulated union it must be of smooth march, but also without play, so that it is possible a silent and vibration-free wash movement.

In the brushes in which, instead of a conventional carrier stirrup structure, joint multiple, to distribute the force of application, which comes from wiper arm, to the washing strip, an element appears  of elastically deformable support, lengthened longitudinally in tape form, on whose bottom face is the ribbon of wash that can be placed on the windshield, the support element it must be provided, on its upper surface with tape opposite the wiper arm, of a component that, equipped with necessary articulation means, serves as half, on the side of the brush, of a coupling whose other half is connected with the wiper arm. To properly satisfy the requirements demanded to the articulation, already described, the axis of the joint must be oriented transversely to the extension Longitudinal of the brush. In addition, the axis of the joint it must also extend transversely to the direction of the force application, which keeps the brush in contact with the glass moon acting on the wiper arm. Normally, such an articulated joint contains a journal of  joint that is attached to the brush or to the arm of the wiper washer. Then, the bearing support housing associated to the joint journal is in the arm of the wiper blades or wiper blades.

In a known device of the type described in the preamble of the independent claim (DE-A-197 29 862), the fixed semi-coupling to the brush is a piece plastic attached to the support element, with two ends of a articulation journal that aligns with each other and leaves the support element. For fixing to the support element, they are arranged in these semi-couplings slots lengths in which the longitudinal edges are submerged external support element. To guarantee a seat according to the stipulations of the semi-couplings in the support element, the longitudinal edges of the element of support should only be rough or equipped with teeth in claw shape. However, it has been shown that a restraint of this type of alternating load, as presented in the movement back and forth during cleaning operation, no It becomes fully satisfactory.

According to the invention, a device is proposed to detachably connect a brush with an arm of the windshield wipers, and the brush itself.

Advantages of the invention

By configuring the semi-coupling by the side of the brush as curved piece of sheet metal it is possible to join this with the element of brush holder, for example, by the procedure accredited spot welding. Such a fixation reliably resists an alternating load. By shaping direct of the articulation journal in this semi-coupling, a stage of intermediate mounting: the clamping of a metal articulated bolt individual in a semi-coupling bracket.

Conveniently, for this it is shaped at least a partial section of the curved piece of rolled sheet in the form of a sleeve as an articulation journal.

You get a configuration of semi-coupling on the side of the brush especially suitable for manufacturing if the curved part of sheet belong base strips attached to the support element, oriented to each other in parallel and separated from each other, which are joined together by a stirrup that presents the joint journal.

In the case of an embodiment, preferred for certain cases of application, of the joining device according to the invention, the articulated journal roll in the form of cuff features two partial sockets that line up with each other, which protrude laterally from the stirrup. By means of the semi-coupling configuration on the side of the brush, you can make a brush that is built low, whose advantages stand out especially with high speeds of vehicle driving

If the support element consists of two elastic rails arranged parallel to each other in grooves longitudinal, open by the edge out, of the slat of washing, a relative movement not influenced by the semi-coupling between the washing strip and the elastic rails if the glass moon to be cleaned presents a curvature that changes continuously. This is guaranteed because the longitudinal axis of the journal of joint is separated from the upper side of the tape of the support element. In this way, among the journal of articulation and the washing strip is enough space for wash strip area, which limits the grooves upwards Longitudinal

To provide good lateral guidance to the brush during your work shift that takes place transversely to its longitudinal extension, in each base strip there is an arm that extends away from the element of support and is oriented in the longitudinal direction of the element of support, so that the arms are arranged apart from each other, seen transversely to the longitudinal extension of the brush, and so that these arms are submerged adapting between the lateral parts, directed towards the brush and provided in arm.

Special advantages are obtained if the fixed semi-coupling to the wiper arm it is preferably arranged at the free end of the arm of the windshield wiper, if additionally this semi-coupling has a cross section in U-shape and the support brackets are configured on the U-sides of this semi-coupling Here, the arm of Windshield wiper can extend completely with an extension beyond the semi-coupling on the side of the wiper arm. That is, the cross section in U shape of this semi-coupling must be placed in the final operating area of the wiper arm, as then, for example, the arms of the base strips of the brush can act in conjunction with the internal faces of the U-arms of the wiper arm in the direction of the mentioned side parts. Then, at the same time, in the U-arms of the wiper arm may also be configured without further measures support housings of the journal.

If in perfecting the invention, in the longitudinal edges opposite each other of the base strips, claw-shaped appendages that surround in the form of clamps the opposite longitudinal edges of the element of support, the security of the union between the element of support and semi-coupling on the side of the brush, since by means of these claws a additional grip action to the support element. In addition, these claw-shaped appendages can serve as guides when this semi-coupling is placed for mounting on the support element.

A configuration of the invention is achieved especially advantageous for certain application cases if the separation of the support element from the longitudinal axis of the journal of joint is at least twice as large as the diameter of the articulation journal, if additionally the base strips are joined with the articulation journal by means of angular supports of the stirrup formed with these and, between the angular supports of the base strips facing each other transversely to the longitudinal extension of the brush, there is a step that is bounded up by the articulation journal. In addition to other distributions, the step that occurs between the supports angles of the stirrup and the articulation journal connected with it  both ends allow the use of the structure of brush already explained, in which the support element has two elastic rails arranged in longitudinal grooves of the slat wash and the upper limit of the slots is reached longitudinal by means of a covering area of the slat wash, which rises above the upper side of the tape of the support element. This space also provides space sufficient for the arm support brackets of the wiper washer.

To obtain a structure especially compact semi-coupling on the side of the brush, it is convenient that the angle brackets are arranged between two appendages in the form of strip clamps base.

An especially good lateral guidance is obtained of the brush during cleaning operation if at each base strip is an arm oriented in the direction longitudinal of the support element and extending away of the support element, if these arms are separated from each other, seen transversely with respect to the extension length of the brush, and if finally these arms are submerge adapting between the side parts facing the brush and provided on the wiper arm.

A particularly advantageous improvement of the idea of the invention provides that the fixed semi-coupling to the wiper arm preferably arranged at the free end of the arm of the windshield wipers, that this semi-coupling has a U-shaped cross section, and that the housings of journal support are configured in a projection present in the U-base, which extends between the two U-arms. Of this shape, you get excellent joint protection against environmental influences since the journal of articulation and support housings of the arm of the arm of the Windshield wipers are housed encapsulated within a space which is surrounded by the two U-arms and the U-base of the arm of the windshield wiper. In addition, the two U-arms can assume simultaneously the function of the side parts mentioned Previously, they interact with the brush arms.

A brush with an elongated support element in the form of a tape for an elastic washing strip like rubber arranged on the lower surface of the tape, on whose surface top of the belt, in the central longitudinal section, is arranged a semi-coupling on the side of the brush to articulate the brush with one arm of the wiper endowed with the other semi-coupling, so that the semi-coupling on the side of the brush has two stands arranged separated from each other, transversely to the longitudinal extension of the brush, for at least one bolt articulated in the form of a journal attached to them, whose axis of joint is oriented transversely to the extension Longitudinal of the brush, can be performed stably easily and permanently join with the semi-coupling on the side of the brush if This semi-coupling is configured as part curved sheet and the articulation journal is conformed with It is forming a piece.

Corresponding to the cases of corresponding application, it may be convenient for the journal of joint is arranged between the two brackets or, however, that the joint journal has two secondary columns that they line up with each other, which are arranged on the faces opposite each other from the brackets and extend moving away from these.

Another advantageous improvement and configurations of the invention are indicated in the description that It follows the realization examples shown in the corresponding drawing.

Description of the embodiments

To a lever 10 of the windshield wiper shown in Figure 1 in side view belong an arm 12 of the wiper, oscillatingly operated from one of its ends 11, and a brush 14 connected therewith in a separable way. The brush 14 is connected to the other free end 13, opposite the 15 axis of oscillation of the wiper arm, so that can perform a swing movement (double arrow 16) with respect to arm 12 of the windshield wiper. The position and the swing axis travel can be seen in figures 3 and 4 and is equipped with reference number 17. As you can observed from these figures, the axis 17 of oscillation is extends transversely to the longitudinal extension of arm 12 of the windshield wiper and also transverse to the direction of a designated force in figure 1 with an arrow 18, which, using the wiper arm, act on the brush 14 and he places it on the crystal moon 19 that will be washed with a elongated wash strip 20, elastic like rubber. The ribbon 20 elongated wash, elastic like rubber is arranged in the lower surface 21 of the belt of a support element 22 of one or more pieces, elastically deformable, elongated in the form of headband. On the other upper surface 23 of the tape, directed to the windshield wiper arm 12, of the brush 14, the lever 10 of the windshield wiper is provided with a connection device 24 to which belong a first semi-coupling 26 by the side of the wiper arm and a second semi-coupling 28 on the side of the brush (Figures 2 to 4). The surface designated in Figure 1 with 19 belongs to a windshield of a generally curved vehicle of spherical shape As can be seen further from Figure 1, the curved brush 14, not yet placed on the moon crystal, has a more intense curvature than the surface 19 of The crystal moon Since line 19 should represent the more intense curvature of the crystal moon surface, can it should be clearly observed that the curvature of the brush 14 still without load, which is arranged with its two ends 30 on moon 19 of crystal, is more intense than the maximum curvature of the moon of crystal. Under effective clamping pressure in the direction of the arrow 18, the brush 14 is placed with its wash strip 20 or with its wash lip 32 set on the wash strip, with its entire length, on the surface 19 of the crystal moon. In addition, in the elastically deformable support element 22, made of metal, a tension is formed that provides a placement as stipulated in the washing strip with all its length on the moon 19 crystal. Since the crystal moon curved generally spherically does not show a section of a spherical surface, the brush 14 must be able to adapt continuously, during its cleaning movement that is performed transversely to its longitudinal extension, to the position corresponding and to the path of the surface 19 of the moon of glass in relation to the cleaning arm 12. This is achieved by the articulated joint between the arm 12 of the windshield wiper and the brush 14 and the necessary oscillation movement mentioned (double arrow 16), with which the brush 14 can swing around the axis 17 of oscillation with respect to the arm 12 of the wiper washer.

Next, it should be treated in more detail the special configuration of a first embodiment of this joint articulated with the help of figures 2 to 4. As Figures 2 and 3 show the deformable support element 22 elastically it has two elastic rails 34, arranged in parallel to each other, found in a common plane. Their internal edges, which are directed towards each other, are in longitudinal grooves 36 that are arranged in the upper zone of the wash strip 20. Elastic rails 34 protrude with its outer 38 longitudinal slots of the grooves 36 longitudinal, so that the upper surface 23 of tape of the support element 22 is directed to arm 12 of the wiper washer. On this upper surface 23 of tape is fixed the semi-coupling 28 by the side of the brush, preferably, soldier. It is configured as part curved sheet and has two base strips 40 arranged in parallel with each other, which are in contact with their side lower on the upper surface 23 of the element ribbon support on the corresponding longitudinal strips 38 and are joined with the support element 22, for example, by spot welding. The base strips 40 extend in the Longitudinal direction of the brush. Therefore, between the two base strips 40 is a so-called zone 42 of washing strip cover 20, which shows the limit upper of the longitudinal grooves 36 (figure 3). The two strips 40 base are joined together by a nerve 44 in the form of stirrup made forming a piece with them, adjoining one with another near one of its ends. Therefore, nerve 44 runs transversely to the longitudinal extension of the brush 14 or transverse to the longitudinal extension of the support element 22. It extends with its two ends beyond the two strips 40 of base. At least, these two ends are rolled in the form of sleeve in such a way that secondary 46 plugs are obtained which align with each other, which protrude laterally over the base strips 40 and serve as articulation sockets (figures 2 and 3). With this, they form extensions of nerve 44 that unites the two base strips 40, which is also shaped in such a way that a rigid joint is formed between the two base strips 40. To the at the same time, the nerve forms a support, for the two gorrones 46 side that form the joint pads, in both 40 strips of base. From figures 2 to 4 it is clarified that the longitudinal axis 17 of the two articulation pins 46 is meets a separation 48 from the upper surface 23 of the tape of the support element 22 (figure 4). In this way, it guarantees a clear free passage of the wash strip 20 under the nerve 44. In its subsequent path, in each of the two strips 40 of semi-coupling base 28 on the side of the brush is pre-curved an arm 50. Both arms extend parallel to each other in the direction length of the support element 22 in the oriented plane vertically on the support element. Also this semi-coupling 28 is endowed in its final zone opposite the nerve 44 of a reinforcing wall 52, which is oriented transversely to the longitudinal direction of the brush and join the two base strips 40 together. The wall 52 of reinforcement, preferably like the two arms 50, is united with these forming a piece, that is, it is conformed with these. Naturally, between the reinforcing wall 52 and the rails 34 elastic is enough space for zone 42 of covering of the washing strip 20, so that it crosses reinforcement wall 52 without touching it. Therefore, you get a curved piece of sheet metal that serves as semi-coupling on the side of the brush, with two base strips 40 that are joined together by a nerve 44. The extensions on both sides of the nerve are rolled in such a way that two pins 46 of joint whose longitudinal axes align with each other. Further, to the semi-coupling 28 belong the two arms 50 formed of a piece in the base strips 40, as well as the wall 52 reinforcement oriented transversely, equally joined forming a piece with the base strips 40.

In the exemplary embodiment, the semi-coupling 26 on the arm side of the windshield wiper is configured at the free end 13 of the arm 12 of the windshield wiper. However, this does not exclude that the arm of the windshield wiper, for example, for design reasons, can be endowed with an extension that extends to the extreme of the brush 14 opposite the wiper arm. So, when we talk about the free end of the arm of the windshield wiper, this always means the section of the wiper arm that is operatively attached to the  operation with the brush 14. As shown in figures 2 and 3, the semi-coupling 26 by the arm side The windshield wiper has a U-shaped cross section. Therefore, it has a U-base 54, on which two are arranged U-sides 56 that are separated from each other, parallel one Regarding another. For reasons of clarity, the semi-coupling 26 is shown in figure 2 in longitudinal section, so that a part of the base 54 in U and of An arm 56 in U are shown with dots and stripes. Figure 3 shows that the opposite ends of each other of the secondary poles 46 or of articulation are arranged with a separation 58 one with respect to another that corresponds to the separation of the two surfaces exterior of the arm 56 in U. The inner walls 60 of the arm 60 U-shaped towards each other they are arranged with a separation 61 one with respect to another, which is adapted to the separation of external surfaces opposite each other of arm 50 of the semi-coupling 28 on the side of the brush, of so that they can submerge, adjusting practically without clearance, as shown in figure 3, between arms 56 U or between the side parts 57 directed towards each other in these U-arms of semi-coupling 26 by the side of the wiper arm. In this way, you get a Excellent brush guide on the wiper arm when the brush moves during your wash job transversely to its longitudinal extension over moon 19 of glass to be washed. The semi-coupling 26 on the side of the wiper arm is made of a elastic plastic In the two arms 56 in U are arranged openings 62 open at the end as support housings for articulation pins 46 directed at free ends of the arm 56 in U. On both sides of each recess 62, the arms 56 in U are provided in each case with slots 64 also open at the end, so that the finger-shaped strips 66  that remain between the grooves and the recess can extend against a recoil force until the pins 46 of articulation can be placed in their configured support points on the sides of the strips 66 directed towards each other when the wiper blade engages on arm 12 of the windshield wiper on the direction of arrow 67. Then, you get a mount that shown in figures 3 and 4. The separation of the brush 14 of the windshield wiper arm 12 is performed opposite to the mounting offset, so that when loading correspondingly the brush 14 opposite the arrow 67, the two strips 66 are separated or deviated elastically from again against the force of recoil, so that the gorrones 46 of articulation can leave the recesses 62 or their journal support housings.

Another embodiment of the device connection according to the invention is explained by figures 5 to 8. Such as shown in figure 5, also here the semi-coupling 128 on the side of the brush It is configured as a curved piece of sheet metal. This one also has two base strips 130 arranged parallel to each other and separated from each other, which extend in the direction length of the brush or support element 122. He support element 122 also surrounds here two rails 125 elastic, oriented parallel to each other and in a plane common, which together form the support element 122. The internal longitudinal sections directed towards each other 125 elastic rails are in longitudinal slots 124 open at the end of the wash strip 120 and protrude with the longitudinal longitudinal strips 123 of the slots 124 Longitudinal On the upper surface 131 of the belt of the Elastic rails 125 or support element 122 are in contact the base strips 130. On the longitudinal edges opposite each other from the base strips meet claw-shaped appendages 132 clamp-shaped the outer longitudinal edges 133 opposite each other of the support element 122. In addition to the setting set as spot welding of the base strips 130 on the rails 125 elastic support element 122, appendices 132 in claw shape improve the bond between the semi-coupling 128 on the side of the brush and the support element 122 when these claws are gripped so correspondent. In addition, Figures 5, 6 and 8 show that the base strips 130 are attached, by means of angular brackets 134 conformed with these, with an articulation journal 136, which it is configured in a stirrup-shaped rib 136 that joins the Angular brackets 134 of the base strips 130. In addition, the angle brackets 134 are arranged in each case between the Appendices 132 in the form of a base strip clamp 130. The separation 137 between articulation journal 135 and the element 122 support is at least twice as large as diameter 138 (figure 6) of articulation journal 135. Between brackets 134 angular, facing each other transversely to the longitudinal direction of the brush, of the base strips 130 on the one hand and support element 122 and journal 135 of joint on the other hand is a step 139 that has a size such that it allows a contactless passage to the coating zone 140 which limits the longitudinal slots 124 of the slat upwards 120 wash. In each of the base strips 130 there is a arm 142, extending away from the support element and is oriented in the longitudinal direction of the element 122 of support, which has two semi-arms, of the that each semi-arm is in one of the two faces of the angular support 134. The two partial arms of each base strip 130 form a corresponding wall in whose Meaning will be entered later.

From figures 6 to 8 the 126 semi-coupling structure on the side of the wiper arm. This one as well semi-coupling has a cross section mainly U-shaped (figure 8). Therefore, it has a base  143 in U to which two arms 144 in U are attached that meet separated from each other. The internal walls directed towards each other of the side parts 145 of the arms 144 in U are located with a separation 146 from each other corresponding to the separation of the two external walls opposite each other of the arms 142. Separated from these inner walls 145, at base 143 in U, they are formed intermediate walls 146 parallel to the arms 144 in U (Figures 6 and 7), so that the separation between the walls 146 intermediate and the arms 144 in U is adapted to the thickness 147 (figure 5) of the arms 142. In addition, at the U-base 143 of the semi-coupling 126 is formed a 150 grip housing, which contains two 151 ears that They can deviate elastically. On the directed internal faces towards one of the ears 151 a housing is configured 152 of the support for the articulation pins 135. The ears  151 made up of one piece in the semi-coupling 126, manufactured from a elastic plastic, they are released, just like strips 66 in the already described embodiment, so that they can be separated until the articulation pins 135 can reach their support housing 152. In addition, the ears are set on the side of the opening such that only one shift assembly, designated by arrow 153 of Figure 6, causes separation of the ears 151 against a force of recoil.

In the operating position shown in the Figures 7 and 8, arms 142, regulated in height, of the strips 130 of base extend in the intermediate spaces in the form of a groove between intermediate walls 146 and arms 144 in U of the semi-coupling 126, so that they are arranged adapting to the side parts formed by intermediate walls 146 directed at them and / or by arms 144 U of the wiper arm. In this way, it provides guidance as stipulated in brush 14 with respect to arm 12 of the windshield wiper. Nerves 154 of reinforcement between the intermediate walls contribute to the stabilization of semi-coupling 126. For remove the wiper arm brush or separate with each other the two semi-couplings 126 and 128, enough with loading the brush against the mounting arrow 153, of so that the articulation journal 135 leaves its housing 152 of support temporarily separating the ears 151.

The two described embodiments of the joint device according to the invention have in common that the second semi-coupling 28 or 128, fixed to the brush, is configured as a curved sheet metal part, with which the articulation pin 46 or 135 is joined forming a piece, conformed with this one.

Therefore, a use of the invention when the wiper blade and / or wiper arm are configured correspondingly to the publication here requested and proportionate in relation to the joint.
